Backup and Restore Runbook (Prototype)

1. What to Backup

1. Repository source (*.model.yaml, policies, docs, schemas, tests).
2. Generated artifacts if needed (gate-report.json, SQL/dbt outputs).
3. UI local workspace export files (if users export snapshots).

2. Backup Procedure

1. Push all branches/tags to remote Git provider.
2. Export release bundle:
3. git archive --format=tar.gz -o release-backup.tar.gz HEAD
4. Store artifact in managed object storage.

3. Restore Procedure

1. Clone repository at target commit/tag.
2. Install dependencies:
3. python3 -m pip install -r requirements.txt
4. cd packages/web-app && npm install
5. Validate integrity:
6. python3 -m unittest -q tests/test_mvp.py tests/test_real_scenarios.py tests/test_integrations.py tests/test_performance.py
7. ./datalex validate-all

4. Disaster Recovery Drill (Prototype)

Run monthly: 1. Restore from latest archive into clean directory. 2. Execute validation, policy, and generation commands. 3. Record restore duration and any missing assets.
